I don't see why some of you are obsessing about the driver size. The size of the driver makes no difference, only the implementation does. Like there is no headphones from other manufacturers with smaller drivers that sound better than Takstar?
Somic shrunk the driver size in their flagships too and people state that it's still an improvement over the previous generation.
Who's obsessed with anything?
In my experience bigger drivers almost always perform better than smaller ones for offerings in the budget segment.
